Jordan Menard's Review Sourced from Google
I came to Faction Studio after two previous developers had completely botched a product. One of them, who supposedly said they won an Omma award, was hired first due to the client's intense specificity and attention to detail.No one was able to deliver - until I went to Faction Studio.These guys are just good at their jobs, it's that simple. They do great work, they work hard, they don't make excuses, and they aren't afraid to go the extra mile.One of the best moves I made in my business was signing Faction Studios, who will be developing all of my future client's websites moving forward.

Confusing technical vocabulary with delivery capability.
An agency can speak the right language in a sales call without having shipped a product at your complexity level.
Buyers get sold on the pitch, skip the portfolio audit, and discover the gap two or three months into a paid engagement when sprint velocity collapses, or early architectural decisions start creating problems that are expensive to reverse.
The way to catch it before signing is to directly ask the agency to walk you through a project that went wrong.
An agency with real delivery experience will talk about the specific decision that caused the problem and what they did differently afterward.
An agency without it will describe the outcome without touching the process.
The proposal is the agency's best effort under zero pressure. If problems appear here, the engagement will have larger ones.
Watch out for some of these warning signs:
An engagement contract should define scope, pricing, revision triggers, milestone timelines, and exit conditions clearly enough that neither party needs to interpret anything.
The clauses most likely to work against you and worth negotiating before signing include:
When two agencies carry comparable credentials, similar pricing, and equivalent portfolios, the deciding factor is almost always how each one behaves during the evaluation process itself.
Test these side by side:
| Differentiator | What a strong answer looks like |
| Account ownership | Named engineer with stated seniority and relevant experience |
| Industry depth | Multiple clients in your sector |
| Risk identification | Specific risks called out about your project |
| Communication cadence | Defined check-in schedule, not "we'll be in touch" |
| Response time | Stated commitment, typically 24 to 48 hours |
| Fee transparency | Written, itemized answer given without hesitation |
| Reference quality | Reference offered without prompting, from a comparable project |
Agencies quote more accurately, onboard faster, and make fewer assumptions when the buyer comes in prepared. Have the following ready before the first conversation:
The last item is underrated, as it allows the agency to understand what you have already attempted and thus spend less of your billable time on approaches you have already rejected.

The decision comes down to what you are building and how long you need to build it.
An in-house hire makes sense when software is a core, ongoing function of the business and will likely require continuous iteration and deeper institutional knowledge. An external hire, on the other hand, makes sense when the timeline is fixed or the technical requirements exceed what a single hire could cover.
If the answer to all these questions is “yes,” then likely a specialized agency is a better fit than an in-house hire:
Software development companies in New York typically charge $100 or more per hour, though rates as low as $40 per hour exist depending on the agency's size and specialization. North American agencies more broadly average $70 to $200+ per hour, with New York firms at the higher end of that range, given local market costs.
Here are some factors that drive price variation:
The quoted number and the final invoice rarely match. Notably, research shows that around 70% of software projects exceed their initial budget, with an average overrun of 27%. The gap usually compounds from several smaller add-ons that were not defined at the start.
The most common “hidden costs” include:
The simplest protection from such overruns is to ask for a written breakdown of every category of work that triggers an additional charge before signing anything.
Not by default, and for most buyers, the assumption works against them.
Larger software development companies in New York bring staffing depth, structured processes, and institutional accountability. For enterprise-level builds with complex compliance requirements, multi-region infrastructure, or large concurrent engineering teams, that scale is genuinely necessary.
For most projects, the dynamic tends to invert: your account gets assigned to mid-level engineers, senior oversight is limited, and the relationship becomes transactional once the contract is signed. The senior developer who impressed you in the sales call may not be the one writing your code.
The more useful question is who will lead your project day-to-day. Ask for the name, seniority level, and relevant experience of the lead engineer and project manager assigned to your account before signing.
Here are some situations that justify switching firms mid-project:
If you decide to switch, you will need: full codebase access and documentation, all environment credentials and infrastructure configurations, a list of open bugs and known issues, and any third-party API keys or service accounts tied to the project. Do not assume these will be handed over without being asked for explicitly; make them a condition of the offboarding.
The best window to switch is between major milestones, after a working build has been delivered and before the next phase begins. Switching mid-sprint, or worse, mid-launch, multiplies handoff risk significantly.
